rIhe pleats give freedom of movement of the float bars and baffles.

What I claim is:

l. In gas or air washers comprising a closed container partly filledwith a liquid through which the gas or air passes, a sheet of flexiblelnaterial in the container below the level of the liquid, a passage forthe gas or air below such sheet, an inlet and outlet for the gas or airto such passage, which is otherwise closed, a series of transverse floatbars secured to said sheet and baffles in said passage dependn ing fromthe said float bars, to interrupt the straight-through passage of the orair, having a freedom of movement, as set forth.

2. In gas or air washers comprising a closed container partly filledwith a liquid through which the gas or air passes, a sheet of flexiblematerial in the container below the level of the liquid, a passage forthe air or gas below such sheet, an inlet and outlet for the gas or airto such passage, which is otherwise closed, a series of transverse floatbars secured to said sheet, sets of relatively rigid depending bafflessecured to said float bars, a longitudinal locating bar on each side ofand inside the container, transverse rods connecting' the lower ends ofthe bailes in each set, and projecting beyond suoli baffles to engagebelow said loeating bars, the baflles in adjacent sets being arranged instaggered relationship, and supports for the float bars allowing thebaffles a small swinging movement, as set forth.

3. In gas or air washers comprising a closed container partly filledwith a liquid through which the gas or air passes, a sheet of flexiblematerial in the container below the level of the liquid, a passage forthe gas or air below such sheet, an inlet and outlet for the air or gasto such passage, which is otherwise closed, a series of transverse floatbars secured to said sheet, baffles in the said passage depending fromthe float bars, to interrupt the straightthrough passage of gas or air,having a freedom of movement, and an adjustable depending baille plateat the inlet to said passage, as set forth.

4l. In gas or air washers comprising a container partly filled with aliquid through which the gas or air passes, a sheet of flexible materialin the container below the level of the liquid, a passage for the air orgas below such sheet, an inlet and outlet for the or air to suchpassage, which is otherwise closed, a series oftransverse float barssecured to said sheet, sets of relatively rigid depending bafl'lessecured to said float bars, a longitudinal locating bar on each side ofand inside the container, transverse rods connecting the lower ends ofthe baffles in each set and projecting beyond such baflles to engagebelow said locating bars, the baffles in adjacent sets being arranged instaggered relationship, supports for the float bars allowing` the baos asmall swinging movement, and an adjustable depending baffle plate at theinlet to said passage, as set forth.

5. In gas or air washers comprising a closed container partly filledwith a liquid through which the gas or air passes, a flexible tarpaulinsheet in the container below the level of the liquid, having a pluralityof transverse pleats at intervals, a passage for the gas or air belowsuch sheet, an inlet and outlet for the gas or air to such passage,which is otherwise closed, a series of transverse float bars secured tosaid sheet between the said pleats, and baffles in said passagedepending from the said float bars, to interrupt the straight-throughj'iassage of the gas or air, having a freedom of movement, as set forth.

6. In gas or air washers comprising a container partly filled with aliquid through which the gas or air passes, a flexible tarpaulin sheetin the container below the levelof the liquid, having a plurality oftransverse pleats at intervals, a passage for the gas or air belowsuoli. sheet, and inlet and outlet for the or air to such passage, whichis otherwise closed, a series of transverse float bars secured to saidsheet between the pleats, sets of relatively rigid depending bafllessecured to said float bars, a longitudinal locating bar on each side ofand inside the container, transverse rods connecting the lower ends ofthe baffles in each set and projecting beyond such baffles to engagebelow said locating bars, the baflies in adjacent sets being arranged instaggered relationship, and adjustable suspension supports for the floatbars allowing the bailles a small swinging movement, as set forth.

7. In gas or air washers according to claim 2, adjustable suspensionsupports for the float bars, as set forth.

In testimony whereof I have signed my name to this specification.

SAMUEL NOEL CHEW.
